The answer is D. They carry out specific functions for a whole organism
Answer:
The observation is an evidence of static electricity.
Explanation:
Static electricity refers to the stationary electric charge that is produced by friction. In other words, this kind of electricity is created when objects (2 objects for example) that are not good conductors of electricity are rubbed together.
During the rubbing process, electrons from the objects come in contact leading to the creation of a stationary electric charge. A good example of static electricity is when you are combing your hair and you see a spark in the mirror.
Answer;
-Presynaptic neuron
Explanation;
-When a nerve impulse travels from neuron 1 to neuron 2, neuron 1 is known as the presynaptic neuron.
-This is a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
- A postsynaptic neuron is a neuron to the cell body or dendrite of which an electrical impulse is transmitted across a synaptic cleft by the release of a neurotransmitter from the axon terminal of a presynaptic neuron.
Reptile scales! Or, more specifically, reptiles descended from dinosaurs.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code. Human DNA has around 3 billion bases, and more than 99 percent of those bases are the same in all people. DNA sequencing theory is the broad body of work that attempts to lay analytical foundations for determining the order of specific nucleotides in a sequence of DNA
